A major part of the premise of the Myst series is that a number of characters in the setting can 'write' worlds (mostly ones you could walk across in a few minutes). The gameplay of the series is built around exploring such worlds, the plots are universally a consequence of the accessibility and exploitation of those worlds, and the major characters are almost always those who either have the ability to write worlds, or who seek to claim that power for their own.
I like this idea, and am looking for an RPG supports it with little modification.
Spcifically, I would like to know if there is a game which places a similar central focus on the creation, exploration and exploitation of worlds by human or humanlike characters, and which has a detailed and workable set of rules governing the creation of smallish worlds, preferably by player characters.
Notes and clarifications:
- Those familiar with the series may be aware that writing an age is not at all the same thing as creating a world, but there are enough similarities that I am willing to let the distinction slide.
- The 'human or humanlike' bit is because I'm not particularly interested in a game where the player characters are gods or god-like. One might argue that being able to crate worlds is automatically god-like, but I'm looking for characters who are more or less mortal in other respects. Well, maybe some spellcasting or something, but let's say... no less mortal that a mid-level D&D character.
- I've not asked a system reccomendation question before, and while I'm reasonably sure I've met the various guidelines, I'd be perfectly willing to believe I've made a mistake somewhere. If anyone has a suggestion as to how this question can be improved, I'll happily re-word it.
- Given the specificity of this question, I suspect I'll recieve only partial answers. Prove me wrong, folks.
